hard wired wifi chip on sdio

[zamek]

Hi All,

I have a Freescale iMX25 based (tx25) board with a Marvell 8688 wireless 
module on sdio bus.
My kernel is a rel_imx_2.6.35_11.03.00 from Freescale git repository.

The wireless chip is hard  wired on sdio bus, not plugged in. On end of 
sdhci_probe_slot() function I call the 
tasklet_schedule(&host->card_tasklet)
to force detecting card.

It seems to be good, mmc0 detected well.

When I try to load wifi module, it failed, cannot download helper binary 
to chip.

I tried to see the sdio bus with an oscilloscope to test it and I need a 
lot of modprobe/rmmod sequence and I wonder, after  the n-th sequence it 
could works well.

It confirms my opinion, there should be an initialization problem, 
because this card is a wired, not a pluggable card.

What is the correct method to force insert card event?

Please either a) use a _recent vanilla_ kernel or b) ask Freescale about their
kernel directly.
